Katy Perry Wore a Sheer Orange Two-Piece Set Littered With a Trio of Keyhole Cutouts

Leave it to Katy Perry to treat American Idol more like a fashion contest than the singing competition it is. From a divisive zebra two-piece ensemble to her sheer, ruffled gown, Perry has proved that her fashion prowess is just as exemplary as her singing skills over the course of the season's 20 episodes — and unsurprisingly, for last night's finale, she ended her parade of her very good looks on a high note.

Combining three sexy trends into a single outfit, Katy shared her OOTN on Instagram and captioned the solo snap, “Orange u glad it was a great #idolfinale? 🍊🧡.” For the show's final episode, the pop star opted for a bright orange, sequined two-piece set by Giuseppe Di Morabito. The plunging crop top featured a trio of keyhole cutouts that were accented by rosettes at the bodice, while the rest of her alluring ensemble featured coordinating high-waisted briefs worn underneath a matching see-through netted skirt. She accessorized with diamond stud earrings and orange crocodile-embossed strappy Aquazzura heels.
